This report describes the case of a 24-year-old female heroin addict with large tricuspid valve vegetation, recurrent septic pulmonary emboli, and renal failure, due to immune-complex nephritis. The clinical course was initially complicated by acute hepatitis A. Because of recurrent emboli and persistent fever despite adequate antibiotic therapy she underwent excision of the vegetation ("vegetectomy") and tricuspid valvuloplasty. She was well at follow-up 12 months later with trivial tricuspid regurgitation shown by doppler-echocardiography. Kidney and liver function were normal. Right-heart endocarditis in drug addiction and therapeutic approaches are discussed. In selected cases "vegetectomy" and valvuloplasty offer a promising therapeutic alternative.

The author has analysed the renal alterations in 8 patients, each of whom died of renal failure. Extracapillary crescents had developed in more than 50% of the glomeruli in all of them. Renal symptoms followed those of endocarditis after two weeks. Proteinuria, haematuria and impairment of renal functional parameters featured the clinical course of the disease. From the haemoculture, bacteria (in 6 cases) and fungus (in one case) were isolated. Haemoculture was negative in one case. The obtained serum complement values, intraglomerular immunoglobulin and/or complement depositions, electron-dense deposits along the glomerular basement membrane and within the mesangium all proved the presence of an immunocomplex mechanism. The rapid course leading to renal failure can be explained by the abundant crescent formation.

The results of combined medical and surgical management of 66 patients with active prosthetic valve endocarditis (APVE) are analyzed. Between 1970 and 1985, 3510 patients were operative survivors of mitral, aortic or double mitral-aortic valve replacement. Cumulative follow-up was 15,640 patient-years (mean 4.4 years). The overall annual incidence of reoperation for APVE was 0.42 +/- 0.05% (0.34 +/- 0.08% for biological and 0.46 +/- 0.06% for mechanical prostheses, p = n.s.). Early APVE occurred in 21 patients and 45 patients had late APVE. Indications for surgery were heart failure in 92%, systemic emboli in 5% and persistent sepsis in 3% of patients. Overall operative mortality (less than 30 days) was 38% (25/66). (Early APVE 52% and late APVE 31%). Anatomical location, valve design and number of prostheses implanted did not correlate with a higher operative risk. Overall endocarditis-related mortality was 56% (37/66). Uni and multivariate stepwise logistic regression analysis identified: 1) date of surgery (p = 0.01), 2) renal failure (p = 0.03) and 3) early APVE (p = 0.03) as predictors of endocarditis-related death. Actuarial survival at 1, 5 and 10 postoperative years was 41 +/- 6%, 30 +/- 6% and 24 +/- 7% respectively. This study confirms the high lethality of APVE. However, with adequate and aggressive combined medical and surgical management, some patients can be saved.

Bacterial infection is a serious and often fatal complication of patients with liver disease and can prove fatal either directly or by precipitation of gastrointestinal bleeding, renal failure, or hepatic encephalopathy. At greatest risk are patients with alcoholic cirrhosis or decompensated chronic liver disease, or cases of acute liver disease who progress to fulminant hepatic failure or subacute hepatic necrosis. Infection appears to be unusual in patients with primary biliary cirrhosis. The site and type of infection is unrelated to the aetiology of the liver disease. Bacteraemia, pneumonia, urinary tract infection and spontaneous bacterial peritonitis are most common but infective endocarditis and meningitis, especially with pneumococci, are easily overlooked. Clinical suspicion of infection must be high as the only indication may be a general deterioration in the patients' clinical state, increasing encephalopathy or renal impairment. In the case of patients with fulminant hepatic failure, infection may precipitate the initial or recurrent encephalopathy and contributes to death in 10% of fatal cases. Spontaneous bacterial peritonitis is now recognized to occur in the absence of clinical features of peritonitis. The PMN content of the ascitic fluid may provide the only indication of infection and is the most readily available screening test. The most common types of organism responsible for all types of infection are Gram-negative enteric and streptococci, especially pneumococci, while infection with anaerobes is rare. Risk factors for infection include decompensated alcoholic liver disease, fulminant hepatic failure, gastrointestinal bleeding, invasive practical procedures and impaired host defence mechanisms against infection. Of the host defence mechanisms, impaired function of the reticuloendothelial system, complement, and PMNs represent the most common and serious defects. Defects of humoral immunity are present in ascitic fluid from patients with cirrhosis and are probably a major reason for development of spontaneous bacterial peritonitis. Diuresis improves these functions and reduces the risk of peritonitis. Treatment of infections even with the appropriate antibiotic is still associated with a high mortality but the use of adjuvant gut sterilization is promising, particularly in cases infected with Gram-negative enteric organisms. Infusions of fresh frozen plasma, blood and cryoprecipitate improve some systemic host defences and may be beneficial in the treatment and reduction of risk of infection.

We have reviewed 108 cases of bacterial endocarditis treated surgically since 1968. The mean age of the patients was 47.7 +/- 15.6 years (+/- SD) (range, 14-79 yr). Seventy-seven percent were male. The most common causative organisms were staphylococci (46%), streptococci viridans group (5%), and other streptococci (20%). Forty-five percent, 25%, and 13% of patients had native aortic valve, native mitral valve, or native double valve (AV/MV) involvement, respectively. Eighteen patients had prosthetic valve endocarditis. No patient underwent surgery for tricuspid valve endocarditis. Seventy-three patients were considered to have active endocarditis (AE) (positive blood or tissue cultures and/or annular abscess). The 35 remaining patients had healed endocarditis (HE). Preoperative complications in patients with either AE or HE were stroke (11%, 11%), renal failure (33%, 3%; p less than 0.001), pulmonary edema (83%, 34%; p less than 0.001), anemia (36%, 8%; p less than 0.01), and inotrope dependence (22%, 6%; p less than 0.05). Hospital mortality for native valve AE was 19.5% (11/56), and for healed endocarditis, 5.7% (2/35). Independent predictors of hospital mortality were inotrope dependence (p less than 0.001), annular abscess (p less than 0.01), pulmonary edema (p less than 0.01), and staphylococcal infection (p less than 0.05). The 5-year actuarial survival for operative survivors was 68.4 +/- 7.5% (AE) and 78.3 +/- 9.2% (HE). We conclude that the operative mortality for patients with continuing sepsis is high and that surgery should be undertaken early in staphylococcal endocarditis. If surgery is successful, then the long-term prognosis is good.

A 40-year-old woman with staphylococcus aureus endocarditis of the mitral valve associated with acute pulmonary edema and renal dysfunction is presented. The patient was admitted to Hiroshima University Hospital with infective endocarditis. On the 14th day after admission, she suffered from severe cardiac failure and oligouria, then she was transferred ICU. Chest X-ray film showed pulmonary congestion and echocardiogram revealed 4th grade of mitral valve regurgitation. Emergent mitral valve replacement was performed and rupture of anterior mitral chorda was found as the cause of acute pulmonary edema. Postoperative care was difficult because of advanced renal failure and cardiac failure not responded to diuretics. Extracorporeal ultrafiltration method was effectively used on the 1st and the 2nd postoperative days and 3000 ml of water was filtered without hemodynamic change. Symptoms of renal and cardiac failure recovered promptly after ultrafiltration. Emergent operative and postoperative use of ultrafiltration method is effective in some cases of infective endocarditis complicated with cardiac and renal failure.

The purpose of this study was to determine the incidence of death as the initial manifestation of cholelithiasis. Records of patients who died or underwent cholecystectomy for gallstone-related disease at Duke University Medical Center between 1976 and 1985 were reviewed. Thirty patients died, six of whom (20%) had previous episodes of biliary pain and stone documentation. Twenty-four (80%) were asymptomatic (three with previous incidental diagnosis of cholelithiasis). Reason for admission included acute cholecystitis (nine), pancreatitis (eight), biliary pain (six), cholangitis (four), jaundice (one), and endocarditis (one). Three patients died of gallstone complications without surgical intervention; one patient had renal failure and two had septicemia. Other causes of death were: sepsis (seven patients), cardiac failure (six), pulmonary complications (four), renal failure (three), cerebrovascular accident (three), liver failure (two), pancreatitis (one), and gastrointestinal bleeding (one). During this period, 1731 cholecystectomies were performed without mortality. In this group, the patients were younger (50 +/- 8 years vs. 64 +/- 13 years, p less than 0.001), and had a lower incidence of cirrhosis (p less than 0.001) and diabetes (p less than 0.002). The sex ratio was inverted (p less than 0.001). This study demonstrates that death from gallstones is uncommon (three cases per year), as is death from their initial clinical manifestation (1.2%). The risk of death is two- and ninefold higher in patients with acute cholecystitis or acute pancreatitis. Age, cirrhosis, and diabetes are important determinants of outcome.

Of three patients with Coxiella burnetii endocarditis, two developed focal segmental proliferative glomerulonephritis (GN), and the third developed diffuse intracapillary proliferative glomerulonephritis. In one case, a good therapeutic response was followed by partial remission of the renal alterations, but 10 months later there were clinical and histological signs of active glomerular nephropathy, suggesting that the antigenic stimulus persisted. In another case, poor evolution of the infection was accompanied by clinically and histologically aggressive glomerular nephropathy, and advanced renal failure. The third patient, who had diffuse proliferative glomerulonephritis, underwent renal biopsy earlier than the other two cases, and the behavior of the nephropathy has not been aggressive to date. Immunohistopathologic study revealed a diffuse granular deposit of IgM and C3 in all three cases; the first two also presented a discrete linear IgG deposit in the capillary loops. Attempts to identify C burnetii antigen at the glomerular level by immunohistologic techniques failed in two patients. The literature on the association of chronic Q fever with glomerulonephritis is briefly reviewed.

Five patients with chronic bacterial infections (two with osteomyelitis, two with infected vascular prostheses, one with soft tissue abscess), but without endocarditis, developed signs of glomerulonephritis and renal failure. Histological examination in three revealed mainly proliferative glomerular alterations. The outcome of glomerulonephritis paralleled the course of infection. Recovery or marked improvement occurred in three patients in whom the infection was cured, one case with smoldering infection eventually developed endstage renal failure, and one with persistent infection died from severe complications with acute renal failure. If renal failure occurs in the setting of suppurative infection, so-called infection-associated glomerulonephritis must be considered. Prompt and effective eradication of infection has an important bearing on the course of renal function.

Twenty patients with necrotizing glomerulonephritis were seen at a general teaching hospital over a 6-year period. These patients represented 5.2% of the histologically verified glomerulonephritis population. Twelve patients had an associated systemic illness (vasculitis in 6, Wegener's granulomatosis in 2, Goodpasture syndrome in 2, infective endocarditis in 1, pulmonary renal syndrome in 1). The clinical course was variable, with equal numbers of patients having rapidly progressive and indolent courses. Four patients (20%) had less than 10% normal glomeruli on renal biopsy and developed end-stage renal failure. Although immunosuppressive and anticoagulant therapy was associated with an improvement in renal function, 6 patients (30%) had died after a mean follow-up period of 25 months.
